The Problem: Connecting a Java App to MySQL
One of the most recent challenges I faced was connecting a Java application to a MySQL database. The application was designed to interact with the database, but it kept failing to establish a connection. After some investigation, I discovered that the issue was related to the MySQL user authentication method.
The Solution: Updating the MySQL User Authentication Method
To resolve the connection issue, I followed these steps:
Open the MySQL prompt using the sudo command:
bash
sudo mysql -u root
Switch to the mysql database:
sql
USE mysql;
Update the user table to change the authentication method for the root user:
sql
UPDATE user SET plugin='mysql_native_password' WHERE User='root';
Flush the privileges to apply the changes:
sql
FLUSH PRIVILEGES;
Exit the MySQL prompt:
sql
exit;
Restart the MySQL service:
bash
sudo service mysql restart
After following these steps, the Java application was able to successfully connect to the MySQL database, and I could continue working on the project.
cd my-java-app
mvn clean install
Starting the JAR Application
Navigate to the target directory of your project:
cd target
Run the generated JAR file:
java -jar my-java-app-1.0-SNAPSHOT.jar
